I'm thinking hard on a quilted Stam, in a lighter color. I wear alot of dark denim though, and am concerned that the blue will rub off onto the bag. I know this is more of a problem for some types of leathers than others. Has it been a problem for quilted Stam owners? I'd really like to hear of other's experiences with this. Thanks, and I apologize if this is in the wrong spot or has been discussed before!
